They took them under their wing.

A large stretch of a Jersey Shore beach is roped off to protect a bird’s nest just in time for Memorial Day weekend.

A pair of American Oystercatchers made their home on the sand in Belmar — and New Jersey Fish and Wildlife is prohibiting beachgoers from trespassing in the area to protect them and their eggs, according to NJ Advance Media.

The agency erected signs at 7th Avenue Beach — one of the most popular spots in Belmar — that say “Do Not Enter,” and explain that the area is a nesting area for the shorebirds, which are protected under federal law.

The placards also warn that “harassing these birds, their eggs or their young” can incur a $50,000 fine or jail time.

The birds are not listed as endangered or threatened species in New Jersey, according to Conserve Wildlife Foundation of New Jersey.

However, their status has been to changed to one of “special concern.”

Many on social media agreed with the agency’s efforts to protect the creatures, which are known for their black and white body and long orange-red bill.

“Love love love this!!!! Beautiful birds! One of my favorite!” one gushed.

“Leave that cute birdie alone people,” another added.

Others thought even more safety precautions were needed.

“We should send a biologist or conservation police to guard the area,” one wrote.

DEP officials told the outlet that the length of time the area would be closed will be determined by whether the chicks opt to remain there after hatching.

If the baby birds decide to relocate to another spot on the beach, that new area will be closed off instead, the agency added.
